Definition

Ostwald ripening refers to the process by which large particles grow at the expense of smaller ones because large particles are more energetically favored (they have a lower surface to volume ratio), while small particles are not energetically stable. As time progresses, the system tries to lower its energy and smaller particles begin to coalesce with bigger ones.
